two characteristics of r-selected species
low parental care, high reproductive rate
two characteristics of a k-selected species
high parental care, low reproductive rate
In a survivorship curve, what type is a r-strategist?
Type III
In a survivorship curve, what type is a k-strategist?
Type I
biotic potential
when resources are plentiful and competition is low
type I description
late loss; juvenile survival is high; longer life spans
type 2 description
constant loss; individuals die at equal rates regardless of age
type 3 description
early loss; high mortality of young, lower mortality in elderly
carrying capacity
the maximum number of individuals of any species that can be
supported by a particular ecosystem on a long-term basis
